SHIP FRAMING Application filed February 9, 1927.

The objects ol this invention are to so an range and construct theframing as to increase the stability of such training, by maltinp; thevertical members continuous and suit ably connected to the main hull andto simplify the construction of a, vessel aiter franr inn is erected bypermitting the work to proceed simultaneously onv any dcclt level or onthe uppermost level, so as to provide shelter and so facilitate theworlc it proceeds later on the lower levels. Also, to increase thestructural eiliciency of the traminp; by assembling: all the members,viz: vertical, horizontal and diagonal of each main transverse frame,into one rigid unit, to which the longitudinal members or girders torthe support oi. intermediate deck beams may be connected.

In accomplishin the objects above set forth. I have found it necessaryand desirable to make certain rather extraordinary changes in the shipconstruction. Such changes will he de cribed in the specification whichfollows and the accompanying drawinns sl'iould be referred to for acomplete understanding of the specification which follows.

In the drawings:

Fig. l is a perspective view showing a 33 means for supportinglongitudinal and transverse girders.

Fig. 2 is an elevation of a section of a ship constructed according tomy invention.

Similar reference numerals indicate like par s in all the figures wherethey appear.

As set forth in the preamble, one oi? the principal objects of thisinvention is to reduce vibration, and another to increase rigidity.

I have found that vibration can to reduced and rigidity increased, bycertain clninp'es in the framing of a ship. These changes consist ofextending the umights as shown at 1, 3 and l as cmitinuous columns ormembers from the main hull structure 5 upward through all of the decks,terminating under the uppermost deck of the superstructure.

In the past, it has been customary to construct a ship in what might betermed units,

the hull and main. deck being constructed and the decl: laid. Theuprights fortlie next deal; are then placed in position and secured, andthe next deck is then applied.

in my system, all uprights from the hull 65 to uiulcr the topmost deckare erected, and

deck beams for all decks are placed in position, and thereafter thedecks are construct- Gil, or arranged upon the deck-supporting means.liy this method of construction, greater rigidity is obtained, and it ispossible to work on all decks simultaneously. In other words, Igenerally follow the principle employed in the construction of steelbuildin arranging all of the framing as the first o :ration, andthereafter securing the plat- 11g and decking, and any other structurethereto, the particular object being to have the upright longitudinaland substantial members continuous, and it because of the hi size oi theship, it is not possible that these members should he formed of onepiece, they shouhl at least be formed so that the sections abut, to besecured so as to form substantially (pntinuons members. Y5

The ship of which I have shown a section of small detailin the drawingsmay be an exclusion boat or river boat, and the decks may be named asfollows; the uppermost deck (3 is the boat deck, directly under the 0boat deck and at 7 is the observatioi'l deck. At 8 I show the salondeck, and the main deck is indicated at 9. As desired, my method offraming may be employed in boats of any (les n or intended for anyparticular op- 55 oration. I show this construction only because of itssimplicity and ease of observation.

The hull frame 5 may be of any shape or outline. It will be understoodthat the frames vary in shape from bow to stern to impart to the hallthe shape desired. The frame 5, then, is selected arbitrarily, andwithout the intention of suggesting that its shape has any importantbearing upon my invention.

The deck members or transverse girders as shown at 9, 10, 11 and 12, maybe supported by any suitable means, such as the channel M bars 13, orthe longitudinal girders 14, shown under the deck 9, the channels 13being supported by angle plates 15. The separate supporting means asshown, are not intended as modifications of supporting means, but areintended to show that each successive lower deck should be provided withincreasingly heavy supports. v

The arched construction employed in Fig. 1 does not change the principleof construction herein set forth as the column portions of the archesextend through for the next lower deck to be received directly upon thenext lower columns or arches, therefore, for r all practical purposes, aportion of the arches merely serves as a continuation of the verticalcolumn.

Theuse of continuous main framing columns makes it possible to employthese columns as ventilating shafts as shown at 16 and 17 in Fig. 1,where ventilators are placed upon the centermost columns. Hollow columnsmay be employed throughout and may serve to facilitate the installationof piping as well as ventilators and may conceal the otherwise unsightlyruns of drainage, heating and air piping, telephone, signal, lightingand other wires and cables.

These hollow columns may have openings or doors suitably arranged asshown at 18 a and without afi'ecting the structural efficiency of thecolumns.

Modifications may be made within 'the scope of the appended claims,without departing from the principle or sacrificing the 5 advantages ofthe invention.

Having carefully and fully described my invention, what I claim anddesire to secure 1. In a multiple deck ship a ship framing 40 havingsubstantially continuous upright members extending from the main hullframing to the uppermost deck which they support and passing through allintermediate decks and having means thereon for supporting suchintermediate decks.

2. In a multiple deck ship a shipframing wherein all uprightsaresubstantially continuous and having their support upon the hull framingand passing through intermediate decks, to terminate under the uppermostdeck and substantially continuous transverse members supported by saidupright members and adapted to support intermediate decks.

3, In a multiple deck ship a ship framing having hollow upright memberssupported upon the hull framing and continuing through all intermediatedecks, and means adjacent each successive deck for supporting said deckupon said upright members.

Signed at the city, county and State of New York, this 3rd day of Sept,1926.
